  • Figure 12B: Composite restorations are ideally suited for internal color adjustments and permit intricate characterizations. The final layer of translucent incisal completes the form.

  • Figure 12A: Composite restorations are ideally suited for internal color adjustments and permit intricate characterizations. The final layer of translucent incisal completes the form.

  • Figure 11: The relative difference in translucency between the enamel and the bright dentin created an excessive contrast at the incisal edge. A brighter opal incisal would have been a better choice here.

  • Figure 10: When the technician selects a pressable ceramic ingot to match bleached dentition, his primary considerations should be value and opacity.

  • Figure 9: Dark preparations and white veneers are a common challenge and usually require deeper

  • Figure 8: Additional emphasis on surface texture and morphology is necessary to make bright restorations appear natural.

  • Figure 7: By including the first bicuspid in this patient’s treatment plan, the inevitable color mismatch between veneers and natural teeth was less conspicuous.

  • Figure 6: The shade of the sample crown on the left central was approved by the patient prior to the fabrication of the 14 maxillary crowns and served as a custom shade guide.

  • Figure 5: In addition to bleached shade tabs, fired porcelain chips are very useful to take accurate shades of white-and-bright dentition.

  • Figure 4: Bleaching is not a viable esthetic option in cases that involve severe staining, existing restorations and tooth-form deficiencies. In this case, porcelain veneers were prescribed.

  • Figure 3: Bleached teeth often fall outside the lightest shades available in the traditional shade guide systems and require new shade-matching modalities.

  • Figure 2: After. Matching bleached shades requires a delicate balance of value, chroma and translucency to defy detection.

  • Figure 1: Before. Matching bleached shades requires a delicate balance of value, chroma and translucency to defy detection.
